Using the Upper() in the index is sometimes problematic because it makes Rushmore optimization a little trickier. (You have to always use the upper() in the operation.) Nonetheless, it is probably a good idea to use it with a client name. Anyway, Quinn - here's the solution all put together and guaranteed to work:

Now:
1. Select Client && Assuming client is the name of your client table
2. Index on Upper(Cl_Name) Tag UCl_name && cl_name is the client name field

Later, in your code:
1. Make sure the client table is in use in Some workarea.
2. l_lRetVal = ;
  Seek(PadR(Upper(txtTextBox.Value),FSize('cl_name','clients'));
  ,'clients','UCl_name')

If that doesn't work, shoot me.
